Abstract (en)

The present invention provides a member coated with a hard coating to attain excellent wear resistance. The hard coating includes: an adhesion reinforcing layer formed on a surface of the member; and a second layer formed on the adhesion reinforcing layer and having a composition represented by the following formula: (AlpTiqVr)(Nu Cv) where 0</=p</=0.75, 0.20</=q</=0.75, 0.10</=r</=0.75, p+q+r=1, 0.6</=u</=1, and u+v=1. In order to further enhance the adhesion of the hard coating to the member, an intermediate layer may be formed between the first and second layers.
